I've just finish readding overview of EF : http://msdn.microsoft.com/en-us/library/Aa697427
And, I find that although we are freed from using sql, but EF bring in esql that we have to use to query entities.
Is it a must to use esql, can we use linq instead to do the same as esql does?
If it's a must, how long will it take to learn enough
